It's probably better to finish Locket of the Iron Solari before Rylais, and in this game I should have. However with 3 melee I used my shield more on others than myself, so the slow came in handy.
Usually I finish up Talisman of Ascencion before any other item. This because of the movement speed and the gold income ofc
So yeah it was an exception pretty much.
The usual build order after the first back (so second back or whatever):
1. Aegis + Boots of Swiftness
2. Locket of the Iron Solari OR Talisman of Ascencion (this depends on your team and your gold income mostly)
But right after you've built one, build the other as well xD
4. A tank item depending on enemy team, or if your team is doing fine just get a ZZ-rot portal for the extra push and both Armor + MR
